Moises Caicedo says his "dream" is to become a "Chelsea legend" after extending his contract until 2033.
The 24-year-old, signed for in excess of £100m with bonuses in 2023, has already won the Europa Conference League and Club World Cup with the Blues.
His now-confirmed new contract – which BBC Sport reported on Thursday – has added two years to his initial deal.
"I am so happy to have extended my contract at Chelsea," Caicedo said. "I believe in this team, this club and I know we're going in the right direction. We've only just begun together.
"There is still a lot more to achieve, and I'm very hungry to keep improving every day. I want to win more trophies with Chelsea and give everything for this club and for the fans.
"We have enjoyed some great times together already and my dream is to become a Chelsea legend, and I will work as hard as possible to make that happen."
